CHARLES REDIVOOD, OF DENISON CITY, TEXAS.

ELASTIC CHAIN.

SPECIFICATION forming part of Letters Patent No. 416,497, dated December 3, 1889.

Application filed November 14, 1888. Serial No. 290,843. (No model.)

To all whom it may concern:

Be it known that I, CHARLES REDWOOD, of Denison City, in the county of Graysonand State of Texas,' have invented a new and Improved Elastic Chain, of which the following is a full, clear, and exact description.

The object of this invention is to provide a chain which will yield longitudinally when subjected to a tensile strain; and to this end the invention consists in the construction and arrangement of parts, as will be hereinafter described and claimed. p

Reference is to be had 'to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a-view of a section of a chain made in accordance with the terms of my in vention. Fig. 2 is a view of the chain as. it appears when under tension, and. Fig. 3 is a perspective view of one of the chain-links.

In constructing such a chain as the one illustrated in the drawings above referred to I take a wire 10, bend it at 2, and at 3, I form eyes adapted to receive the body of the adjacent link,

In practice I prefer that the links should approximate the form shown in the drawings; but I desire it to be understood that any proper form of link which would yield under tension could be employed without departing from the spirit of my invention.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent- 1. An elastic chain consisting in flexible wire loops having eyes at their ends and bulging or bowed between their ends, the body of one loop being passed through the eyes of the adjacent loop, and all of said loops being placed fiatwise, or in the same plane, substantially as set forth.

2. A chain made of links, each link consisting of a length of wire formed with eyes or loops at each end receiving the body of the adjacent link, and each link shaped to contract perpendicularly and expand longitudinally when under tension, the eyes of one link sliding toward each other on the link passing therethrough and away from its eyes when strain is applied to the chain, thereby increasing the whole length of the chain, and the length of the chain being contracted by the lateral or perpendicular expansion of its links when relieved of strain, substantially as set forth. 7
